I know with 16.04 it wasn’t used by default. I had to do a lot of manipulation
to set up the raid array before I could do the install. It used dmraid once it
detected the imsm raid. I removed dmraid completely, then installed mdadm,
assembled the array & ran the installation program again. I was hoping that
mdadm would just do it all instead.
